To all whom it may OOILOGIIL:

Be it known that I, THOMAS A. human, a citizen of the United States ofAmerica, and

a resident of Cambridge, in the county of Middlesex and State ofMassachusetts, have invented certain new and useful Improvements inPlaningi\lacliiiies, of which the following is a specification.

This invention relates to planing-machines,

ro and has for its object the production of a machine in which a specialtool is provided and mechanism supporting said tool which may beactuated at the end of movement of the tool in either direction tochange its angle 15 and cause a cutf'ng in either direction of movementof the work upon which said tool is operating.

The invention consists in certain novel features of construction andarrangement of parts, which will be readily understood by reference tothe description of the drawings and to the claims to be hereinaftergiven.

Of the drawings, Figure 1 represents a side elevation of aplaning-machine embodying the features of this invention. Fig. 2represents a front elevation of the tool-supporting head. Fig. 3represents a vertical section on line 3 3 on Fig. 2. Fig. 4 represents aplan of the same. Fig. 5 represents a partial horizontal section on line5 5 on Fig. 3. Fig. 6 represents a plan of the upper end of thetool-support in diagram. Fig. 7 represents an elevation and plan of theend of the working tool in position to operate upon the work when beingfed in the direction in dicated by the arrow, and Fig. 8 representssimilar views of the same tool in position to operate upon the work whenbeing fed in the opposite direction.

Similar characters designate like parts throughout the several figuresof the drawmgs.

1n the drawings, 10 represents the main frame of a planer of anywell-known con struction, while 11 is the work-supporting bed movablelongitudinally of the frame 10 in any well-known manner. To the crossrail 12 of said planer is secured the head 13, to the front of which issecured by suitable bolts H the tool-holder 15. The holder 15 has cutthcrcthrough a vertical slot 16, the width of which is equal to thediameter of the shank 17 of the tool-support 18, the

lower end of which is spherical, as at 19, and provided with a recessfor the insertion of 5 5 the working tool 20. The lower end of the slot16 is provided with a recessed socket 21, adapted to iit the sphericalend 19 of the tool-support 1S and provide a universal joint therefor.

The upper end of the shank 17 has a bearing in a slide 22, the lowerface of which is concentric with the center of the spherical end 19 andis slidable upon the outer concentric surface 23 of the tool-holder 15.The shank 17 has secured to its outer end the nut 24 and check-nut 25,by which the friction upon the slide 22 and end 19 may be adjusted.

The upper end of the slot 16 is elongated longitudinally of the planerand tapers grad- 7o ually to the recess 21. To the face of the upper endof the shank 17 is secured a grooved plate 26, with the groove 27 ofwhich a pin 28 engages. This pin is secured to the member 29, pivoted at30 to a slotted support 31. The pivot 30 is provided with a nut 38*, bywhich said pivot may be adjustcd longitudinally of the slot- 32 of saidsupport 31 to vary the movement of the tool, as will be hereinafterdescribed.

Slidable upon the member 29' is a member 33, the outer end of which isprovided with a hole 341, engaging a pin 35, supported by a lever 36,pivoted at 37 to the car 38, extending from the head 15. The upper endof the 8 5 pin 35 is provided with a block 39, to which is pivoted thelinks 10, the opposite ends of which are pivoted to a block 11, securedto or forming a p art of the upwardlyextending lever 12, mounted upon anoscillating shaft 43. The shaft 13 is provided with a lever 14, to theouter end of which is secured a rod &5, upon which is adjustably secureda sleeve 4.6, said sleeve being pivoted to a friction member 17,provided with a pin 18, which limits 9 5 the movement of the frictiondevice 47 in either direction by coming in contact with the pins 49 50.This friction device is the same as will be found on any well-knownplaner and affords a ready means of operat- Ico ing the rod -15 tooscillate the shaft 43, which is mounted in suitable bearings 51 uponthe tool-head 15. The slot 16 is provided with a lateral opening 52,communicating therewith and extending through the wall of the head 15,and the shank 17 is provided with a ported by a chain 61, is provided,which ma be inserted through thehole 62 in the head 15 and through theslot 62* in the shank 17, this slot 62* being of such a length as toper- I mit the shank 15 to be freely moved in a vertical plane, butmaking it impossible to turn the same upon its axis when said pin 60 isinserted in said slot. The movement of the actuating parts in excess ofthe movement of the tool-support 17 when thus blocked is cared for b ythe friction device 47 in a wellknown manner.

' The lateral and vertical feeds to the head form no feature of thepresent invention, and may be constructed and operated as in anywell-known planing-machine, and for this reason in order to simplify theunderstanding of lateral projection 53, which extends into this opening52.

To suitable ears 54 upon the head 15 are secured adjustable stops 55,which limit the horizontal movement of said projection 53 when movedabout the axis of the shank 17. j The end of the tool 20 is of the shapeshown in the lower part of Figs. 7 and 8, and either corner 56 57 isadapted to out upon the Work passing beneath the same according to thevertical angle of said tool 20, as indicated clearly in Figs. 7 and8that is, when the bed 11 is traveling in the direction of the arrow 58with work secured thereto and passing beneath the tool 20 the edge 56will operate upon said Work to cut the same. When, however, travel ofthe work is reversed and is moved in the direction indicated by thearrow 59 on Fig. 8, the cutting edge 57 will coact therewith and performthe same operation in the reverse movement. This reversal of thevertical and horizontal angles of the cutting-tool 20 is accomplished bymeans of the devices heretofore described through the medium of theoscillating fric tion member 17 acting upon the rod 45 to produce anoscillation of the shaft 43. The oscillation of this shaft 43 causes thepin 35 to be moved horizontally toward or awa from the head 15, therebycausing the member 29 to be moved about its pivot 30. his movement ofthe member 29 will cause the pin 28 thereon to operate against the sidewalls of the groove 27. This action of the pin against the wall of thegroove 27 will tend to move the shank 17 from the position shown in Fig.3 into its opposite position with its front side against the oppositewall of said recess 16. As soon as the shank 17 reaches 1. In aplaning-machine, the combination the limit of its vertical movementabout the with a tool-holder suitably mounted in the socket 21 acontinuation of the movement frame thereof, of asingle working toolhaving of the pin 28 against the wall of the groove two cutting edgesoppositely inclined from a 27 will cause the shank 17 to be rotatedabout vertical face common to both and adapted to its aXis, moving theprojection 53 from the cut in either direction, and means forchangposition shown in Fig. 2 to the opposite side ing the angle of saidtool-holder about its of said opening 52 to cause its opposite facelongitudinal axis at the end of the movement to contact with the end ofthe adjustingin either direction to change the angle of said screw 55 atthe left of said figure, this movecommon face to the work andalternately ment causing the working tools 20 to be bring a differentcutting edge into operative moved into the position indicated in Fig. 7.position.

A reversal of these movements will cause the 2. In a planing-machine,the combination tool 20 to be moved into the position indiwith atool-holder suitably mounted in the cated in Fig. 8 and shown throughoutthe frame thereof, of a working tool adapted to figures of the drawings.By adjusting the cut in either direction, and means for changmember 29in the support 81 so that the pin j ing the vertical and horizontalangles thereof 28 will be on the opposite side of the axis of j at theend of movement in either direction. said tool-support 18 the movementsof said 3. In a planing-machine, the combination members will bereversed. When it is dewith a tool-holder suitably mounted in the siredthat a channel should be cut into the frame thereof, of a working toolsupported work of the width of the working tool 20, it is therebyadapted to cut in either direction, obvious that the horizontal anglechanging j mechanism cooperating with said working is not desirable andthat the vertical angle j tool for moving it through a vertical angle,change is all that is necessary. To prevent stops for limiting saidvertical movement,

this horizontal angle change, a pin 60, supand means cooperating withsaid mechanism thereof are omitted from the drawings.

In order to strengthen the spherical end 19 of the tool-support 18, itis provided with a transverse member 63, having a head 64 on one endthereof, while the other end is threaded to receive a nut 65, by whichsaid member may be secured in position to prevent the splitting understrain of said tool-support when the tool 20 is in operation. The member63 is provided with a hole 66, through which the tool 20 is inserted,this tool 20 being held in position therein by means of the set-screw67. This forms an important feature of this invention, as it strengthensthe tool-support and prevents it from becoming injured and making theplaner inoperative.

It is believed that from the foregoing the operation of the inventionwill be thoroughly understood without any further description.

I claim the present invention many of the elements.

for causing said tool to be moved through a horizontal angle.
